Abstract
This utility model relates to a kind of battery bag, belongs to electrical equipment technical field.This battery bag includes the shell containing battery that the involutory housing of at least two is constituted, and one of the most described housing has at least localized metallic radiator structure, and described radiator structure inside and battery terminal contact, described radiator structure outer surface is exposed in air.Radiator structure of the present utility model is not limited to by housing, and area significantly increases, therefore better heat-radiation effect；And without individually considering the location of radiating piece, therefore simple in construction, easy to assembly, take up room little.
Description
Technical field
This utility model relates to a kind of heat abstractor, especially a kind of battery bag, belongs to electrical equipment technical field.
Background technology
In order to suppress the heating of power tool battery bag as far as possible, thus ensureing that it normally works, increase the service life, battery bag is generally provided with radiator structure.Typical battery bag radiator structure, as disclosed in U.S. Patent application US2014272516A1, is characterized in bottom battery unit contacting with heat sink, and has the round making heat sink be exposed to air bottom battery bag.
This existing radiator structure is limited by housing size, and the radiating piece area of dissipation Chang Buneng under like products volume meets actual demand.This radiator structure assembling simultaneously needs to consider location and the installation of radiating piece, comparatively laborious, and takies product space.
Utility model content
The purpose of this utility model is: the problem existed for above-mentioned prior art, and a kind of area of dissipation of proposition is big, excellent in heat dissipation effect, and the battery bag that compact conformation, assembly process process are good.
In order to reach object above, battery bag basic technical scheme of the present utility model is: include the shell containing battery that the involutory housing of at least two is constituted, one of the most described housing has at least localized metallic radiator structure, described radiator structure inside and battery terminal contact, described radiator structure outer surface is exposed in air.
Compared with prior art, radiator structure of the present utility model is not limited to by housing, and area significantly increases, therefore better heat-radiation effect；And without individually considering the location of radiating piece, therefore simple in construction, easy to assembly, take up room little.
Further, described shell includes box-like lower house and upper shell, and the opening part of described lower house installs metal upper shell body, and the periphery of described upper shell and the edge of opening of lower house form identical cover-buckling structure.
Further, the upper surface of described upper shell has the radiating ribs being exposed in air spaced apart.
Further, described upper shell inner surface is intervally distributed with semi arch notch, and the inner surface of described semi arch notch is directly contacted with battery or contacted by heat-conducting medium.
Further, the inner surface of described upper shell is intervally distributed with polygon notch, the inner surface cut-grafting direct with battery of described polygon notch or contacted by heat-conducting medium.
Further, the inner surface of described upper shell is plane, by the heat-conducting silicone grease filled and battery terminal contact.
Further, the inner surface of described upper shell is intervally distributed with the circular hole accommodating battery, and the inner surface of described circular hole is directly contacted with battery or contacted by heat-conducting medium.

Detailed description of the invention
Embodiment one
As shown in Figure 1, 2, 3, shell includes box-like lower house 1 to the battery pack structure of the present embodiment, and this lower house 1 opening part installs the upper shell 3 of aluminum matter.The periphery 3-3 of this upper shell 3 and the edge of opening of lower house 1 form identical cover-buckling structure, and its inner surface is intervally distributed with semi arch notch 3-1, and its upper surface has radiating ribs 3-2 being exposed in air spaced apart.The inner surface of semi arch notch 3-1 is directly contacted with battery 2 or is contacted by the heat-conducting medium 4 of heat-conducting silicone grease or heat conductive pad etc.
Test shows, the battery bag of the present embodiment has a following remarkable advantage:
1. significantly increase due to radiating piece area, housing itself, therefore good heat dissipation effect need not be confined to, can conscientiously meet actual demand.
2. radiating piece assembling is simple, takes up room little, it is not necessary to individually considers assembling and the location structure of radiating piece, therefore manufactures and packaging technology is good.
Embodiment two
As shown in Figure 4, basic structure is identical with embodiment one, and difference is for the battery pack structure of the present embodiment, and the inner surface of upper shell 3 is intervally distributed with polygon notch 3-1.The inner surface of polygon notch 3-1 cut-grafting direct with battery 2 or contacted by the heat-conducting medium 4 of heat-conducting silicone grease or heat conductive pad etc.
Embodiment three
The battery pack structure of the present embodiment is as it is shown in figure 5, basic structure is identical with embodiment one, and difference is, the inner surface of upper shell 3 is plane, and the heat-conducting silicone grease 4 by filling completely contacts with battery 2.
Embodiment four
The battery pack structure of the present embodiment is as shown in Figure 6, basic structure is similar with embodiment one, difference is, lower house 1 inner bottom is plane, the perforation 3-1 of the bottom arrangement spaced apart battery 2 of upper shell 3, the heat-conducting medium 4 of perforation 3-1 inner surface thermal contact conductance silicone grease or heat conductive pad etc direct with battery 2 contacts.
In addition to the implementation, this utility model can also have other embodiments.Such as, the housing of heat radiation can also not be entirely heat dissipation metal material, but the various material combinative structure formed based on metal material and by modes such as injection, screw assemblings, etc..The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of this utility model requirement.
